The very idea that experiencing miracles warrants a lack of concern about heresies is itself heretical.
Miracles are evidence of the power of God. Assurance comes from knowing Him. To repeat what I said at post 14961:
So, no, I am not concerned about heresies – either my beliefs or those of my beloved Catholic relatives. I have cast all of my burdens on Him, I have thrown all caution to His wind. My fate is in His hands. I choose to believe Him, to trust Him, to count on Him.
My Catholic relatives are not heretics. My Protestant relatives are not heretics. I am not a heretic. We have some differences on the details – much like we would see different things if we were facing different facets of the same, seven faceted diamond. But we all know that it is the same diamond and the same Light.
You cannot love Christ and not love Truth. If you love Christ, you will hate false teaching about Him.
There is no hate in me to muster. But I am always quick to speak up when something or some one is being glorified above Him. And, of course, I speak up any time the Spirit leads me to do so. Do you remember that old cartoon of the little Chihuahua boldly barking when he stood between the legs of the big Bulldog?
Metaphorically speaking, why would I hate or fear or get offended by or attack what is in front of me when I know Who is behind me?
Then he answered and spake unto me, saying, This [is] the word of the LORD unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the LORD of hosts. – Zec 4:6
